STEP 5: COORDINATE RESOURCES AND PLAN RESPONSE OBJECTIVES Offensive—An aggressive attempt to solve
the problem. To be in an offensive mode, there must be extensive resources and high-level skilled responders to mount an aggressive at- tack on the incident. There must also be a high level of benefit (rescue of live victims, shutting the valve, and ending the release) to justify the risks of an offensive mode. There is no question: being in an offensive mode creates extensive risks to personnel; in isolated situations, how- ever, the mode may be justified if the success (outcome) can offset the extreme risk. Respon- ders must never be in an offensive mode for lit- tle or no benefit.
Defensive—This mode is used when re-
sources and/or capabilities are limited. There is risk, but responders minimize the risk by using distance, safer operations, and limited exposure time while there is still a great deal of benefit to be gained. Defensive tactics can also buy time during an evacuation. An illustration: when firefighters cool a major building that is being exposed by a large gas release and fire from a broken line in the street. There is risk, but there is also a great benefit by preventing the incident spreading to exposures.
Nonintervention—In many flammable gas
events, there is little or no benefit from any strategic effort and nonintervention is a viable tactic. The obvious choice, then, is to let the in- cident run its natural course and not intervene. If nothing is to be gained, nothing should be risked. Let it burn off, or burn out (if possible) and then begin operations when the hazards are reduced.
FIGURE 4.14 Nonintervention actions. Step 6: Implement Response Objectives
Strategic response objectives need specific tactics if they are to be successful. Responders need to know that it is not enough to identify the goal; there must be a method of implementing successful actions to achieve that goal. If the goal or objective was life safety, then the actions/tactics used can be rescue,
